Well, CL.EXE works pretty well on Wine too.... It _technically_ breaks a few terms of the EULA, but that's not too bad though.

This works pretty well: https://github.com/mstorsjo/msvc-wine

Use it alongside something like this CMake toolchain file:

set(CMAKE_SYSTEM_NAME Windows) set(CMAKE_SYSTEM_PROCESSOR amd64)

    set(CMAKE_C_COMPILER cl)
    set(CMAKE_CXX_COMPILER cl)
    set(CMAKE_AR lib)
    set(CMAKE_LINKER link)
    set(CMAKE_MT mt)

    set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
    set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
    set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
    set(CMAKE_FIND_ROOT_PATH_MODE_PACKAGE ONLY)

after adding the various scripts to path.

If you want to speed up a little you can use `clang-cl` with the MSVC libraries, and it will work fine too.
